Abstract (en)
[origin: WO2008142210A1] A light emitting device (400) including an array of light emitters (E1 ) to emit first light pulses (B1 ). Each of the light emitters (E1 ) includes a saturable absorber (40) and a waveguide (24) having an electrically pumped gain region (20) to emit the first light pulses (B1 ). At least one reflector structure (50) reflects the first light pulses (B1 ) into a nonlinear crystal (140) by changing the direction of the first light pulses (B1 ) by an angle that is in a range of 70 to 110 degrees. The reflector structure (50) includes a sub-wavelength grating structure (52) to change the polarization of the first light pulses (B1 ). A nonlinear crystal (140) generates second light pulses (B2) such that the optical frequency of the second light pulses (B2) is two times the optical frequency of the first light pulses (B1 ).
